The folks at Arts San Antonio kick off The Joffrey Experience series — designed as a warm-up to the March production of “The Rite of Spring” by the Joffrey Ballet — this week. First up is “Champagne and Cinema,” a swanky evening built around a screening of “Joffrey: Mavericks of American Dance,” a documentary about the Joffrey Ballet, co-founded by (from left) Gerald Arpino and Robert Joffrey. The evening begins with a Champagne reception, followed by an introduction of the film by Linda Hardberger, honorary chairwoman of the Joffrey Experience, who will place “Rite of Spring” into a historical context.
